Examples of ij.gui.GenericDialog.addDialogListener()

ij.gui.GenericDialog.addDialogListener()
Add an Object implementing the DialogListener interface. This object will be notified by its dialogItemChanged method of input to the dialog. The first DialogListener will be also called after the user has typed 'OK' or if the dialog has been invoked by a macro; it should read all input fields of the dialog. For other listeners, the OK button will not cause a call to dialogItemChanged; the CANCEL button will never cause such a call. @param dl the Object that wants to listen.
